"Original application filed Januaw 13, 1911, Serial No. 602,532. Dividedand this application filed December 18, 1912. Serial No. 737,403.

To all whom it may concern Be it known that I, BENJAMIN D. CHAM- BERLIN,a citizen of the United States of America, and a resident of Corning,New York, have invented certain new and useful Improvements inGlass-VVorking Apparatus, of which the following is a specification.

This is a division of my prior application filed January 13, 1911,Serial No. 602,532 (which has since the filing of this applicationissued into Patent 1,124,698, dated Jan. 12, 1915) and its purpose is tocover certain improvements in marvering mechanism disclosed in my saidprior ap: plication and particularly applicable to the machine describedtherein, although susceptible of use with other machines wherein a glasscarrier having a rough and irregular body of glass thereon is moved formarvering the glass to work it into a solid homogeneous blank of propershape and then moved to efiect other operations in the pro ductions ofthe finished article.

The particular machine forming the sub ject-matter of my priorapplication, Serial 'na-eoassa, filed January 13, 1911 (Patent No.1,124,698) has a pivoted blow-pipe carrier-adapted to receive and rotatea removable blow-pipe with a solid gatherer thereon, and adapted to bemoved on its pivot to cause the glass to be brought into contact with,and rolled along, amarverer on which it is ma'rvered and properly shapedso that upon elongation it will be of a proper character to form thedesired article when blown, after which the blow pipe is positioned formolding.

Inasmuch as the mechanismsto be here covered relate merely to themarvering of the gather on the glass carrier to produce the solid blankof the desired shape and character, so much of the mechanism of my 0i'ginalapplication as relates to other feares and to the construction ofthe other 'parts of the apparatus are capable of variation at will, andit will .be understood thatthedetails of construction here disclosedencez-Figure 1 is a side elevation of the marverer and the glasscarrier, its support and the operating mechanism whereby the glasscarrier is moved for marvering and positioned for further functions,part of the mechanism being shown in dotted lines. Fig. 2 is a plan viewof Fig. 1, parts being broken away to facilitate the showing. Fig. 3 isa section on the line XX Fig. 1.

Suitably carried in the bearing 2 is a trunnion 3, having on its rearend a gear 4 meshing with a rack sector 5 which reciprocates through alimited arc. Mounted on the forward end of the trunnion and fast theretois the supporting frame 6, adapted to receive the glass carrier, shownin the form of a removable blow-pipe A which is adapted to be moved andpositioned with the glass thereon for the several operations by themovement of the frame effected by the rack sector 5 and the gear 4.Means for rotating the glass carrier are provided, which means comprisea beveled pinion 40 driven in any suitable manner and mounted upon thetrunnion and meshing with and driving a beveled pinion 39 which in turndrives, by means of the pinion 39, the blow pipe. A skeleton frame 7 isfixed to the bearing 2 by means of the shoulder 8 and projects forwardlyand upwardly from thebearing 2, preferably at an angle of about 15.

Mounted on the outer end of the frame 7 in any appropriate manner is anL frame 10 upon which is fastened a block 11 which is adapted topivotally suppbrt a marverer 12 by means of a vertical pivot 9. Themarverer is so located that upon the upward movement of the glasscarrier with a gather of glass thereon, the latter will roll upon theouter surface of the plate.

At the completion of the upward movement of the glass carrier, and priorto its return, it is desirable that the marverer be kept out of contactwith the glass on the glass carrier and for that purpose the fllowingmeans are employed: Mounted on the lower end of the frame and adjacentto the bearing 2 is a depending block 14 ,through which passes a shaft15, the said shaft having on its upper end a lever 16 projectingrearwardly and entering a recess 17 in a longitudinal link 18 projectingoutwardly behind the marverer frame from which it is slidingly carried.In the outer end of the longitudinal link 18 is a recess 19 throughwhich is adapted to pass an arm 20 which is fast to the marvering plate12. It will be here noted that the rotation of the shaft 15 will causethe rod 18 to move axially, and by means of the arm 20 cause thenecessary movement of the marverer 12.

v On the lower end of the shaft 15 and below the lower end of thedepending block it is an actuator 23 having upon its inner end a roller29 adapted to engage a crown cam 28 upon'theforward face of the racksector 5. Upon the oscillation of the rack sector .5 in an outwarddirection (see arrow Fig. l) tocause the upward movement of thesupporting frame with the glass carrierand a gather of glass thereon andabout the end of such oscillation, the cam roller 29 will climb the faceof the cam 28, and through the rod 18 cause the marverer to moverearwardly and away from the plane of movement of the gather of glass.As the rack sector 5 reaches the outward limit of its oscillation andthe roller 29 reaches the highest point on the crown cam, a latch 21pivoted to the depending block 14 at 22 will catch the actuator 23 andhold it in the position it assumes when the roller is at the highestpoint on the crown cam 28.

By proper mechanism, completely illustrated in my prior application,Serial No. 602,532, filed January 13, 1911, (Patent No. 1,l2l,698) butnot deemed necessary to be shown here, the rack sector 5 is then causedto move in' an inward direction thus causing the reverse rotation of thegear 4:, this rotation causing a reverse movement of the trunnion 3 and.hence a downward movement of the supporting frame with the glass carrierwith the gather of glass thereon to position it for other necessaryfunctions such as elongation, blowing and molding. Upon the completionof the reverse movement of the sector 5, the latch 21 is released by anarm 24- upon the sector and which, engages with the latch 21, raisingthe same whereupon the marverer will be thrown to its normal positionfor the marvering of the next gather of glass, by an expansion spring 25surrounding the rod 18 and havmg one end bearing against a bracket 26and the other end against a collar 27. It

' willhere be seen that the spring 25 also serves to resiliently holdthe marverer against the gather of glass on the glass carrier during theinarvering.

It will be noted that in the operation of the mechanism here shown, aglass carrier which, in the specific form shown comprises the usualhollow blow pipe, and having thereon an irregular and undetermined solidmass of glass, is moved along a smooth surface and rolled thereon whilein movement, eliminating sliding motion between the glass and themarvering surface. This results in a gradual working of the glass to amore or less cylindrical form with a consequent gradual reduction indiameter and an increase in the density and homogeneity of the glass,and this reduction in the diameter of the glass necessitates a relativemovement between the marverer and the plane of movement of theglass-carrier which, in the construction shown is provided for by thespring Thus the blank whenit has reached its upper limit of movementalong the marvercr has beenproperly shaped and -as at the completion ofthe upward movein combination tith a n'iovement of the glass along themarvering surface, or a movement i the marvering surface past the glass,during marverin as such matter is disclose in my prior a-pplications.serially numbered 491,812, filed April race, and 551,198, fins h'l'arch23, 1910, and will he claimed therein with other matter common to thisand such other cases, but the claims of this applies-- tion arerestricted to moving the marverer away from the plane of movement of theblow-pipe after theinarvering has been done, so that the marvered blankcan be reversed in its translatory movement and move,past the marvererwithout contacting therewith.

Having thus described my invention what I desire to secure by LettersPatent is 1. In a glass working machine, the comhination with a rotatingglass carrier, of a marverer, means for moving the lass carrier to workthe glass containe thereon upon and along the surface of the marverer,
